fflate VS WASM-ImageMagick

Or fflate

Another operation that is sometimes desired is to take several files and give the user a compressed file. There are actually a surprisingly large amount (jszip, pako) of client side options here, but my favorite so far when it comes to speed, size and working with .zip has been fflate. But if you'd like to work with other formats, there are also libraries to decompress 7-Zip, RAR & TAR.

I started my file system with BrowserFS which allowed me to setup IndexedDb as the main writeable location. When in Firefox Private mode it switches to an in memory file system which does not persist. Using BrowserFS also meant I could open ZIP and ISO files as if they were folders. I create a JSON file on build that has the initial public folder directory structure which is used as the readable portion of the file system via plain HTTP GET requests. I've also added the ability to extract RAR files, although I don't currently have it linked to File Explorer to see it's contents before extracting. I can also make and extract ZIP/ISO via fflate.

Hello all! I've been maintaining fflate, a pure JavaScript compression and decompression library for DEFLATE data, for nearly a year now. It's become quite popular for being the fastest DEFLATE library available (including WebAssembly ports!) while being absolutely tiny in terms of bundle size. DEFLATE has many uses, as a general purpose compression format, so it has become very popular and is used in formats like PNG, PDF, XLSX, etc.

To keep it short: I've worked on Parcel for a few months and therefore have investigated in great depth the fine details of making a package bundler-friendly. I've also published and maintained various successful packages, the most popular of which is is a high-performance compression library that reached over 4 million downloads in 6 months and is currently depended on by large projects such as SheetJS and Three.js. I've dealt with many of the problems new library authors face multiple times, so I'm familiar with the workarounds.

Image Conversion via WASM-ImageMagick

I've gone with ImageMagick ported to WebAssembly to do basically the exact same things as with FFMpeg, but with a tiny bit less locking up. In the future I would like to get these things running in multithreaded Web Workers as well as have the ability to easily configure transcode settings to whatever is desired instead of the defaults as it is now.

When it comes to audio/video the trusted tool that is often used on the desktop is FFmpeg and this too has been ported to run in the browser, although if you want multithreading you will need to make sure you have special CORS headers enabled to gain access to the SharedArrayBuffer. For images on desktop there is the popular ImageMagick which indeed also has been ported.

ImageMagick is the go to for these kinda things and apparently there is a WASM version: https://github.com/KnicKnic/WASM-ImageMagick
